Very interesting perspective and thanks for documenting it so clearly. That illustration alone should be enough to convince any class 3 doubters, especially so when you factor in index linking.So I’m getting more than double by paying the voluntary NI
By the time you personally are drawing the pension (at age 67) the weekly benefit from one year’s NI contribution goes up from £6.89 now to nearer to £10 (assuming minimum annual uplifts of 2.5%).
